How to check if Specified Element is present in the Array in Ruby ?

Answer

To check if a specified element is present in an array in Ruby, you can use methods like include? or a loop to iterate through the array and check each element.

✐ Examples

1 Check if Element 30 is present in Integer Array using include?

In this example,

We create an integer array named numbers with values 10, 20, 30, 40, 50.
We use the include? method to check if element 30 is present in the array.
The include? method returns true if the element is found, otherwise false.

Ruby Program

numbers = [10, 20, 30, 40, 50]
element = 30
is_present = numbers.include?(element)
puts "Element 30 is present: #{is_present}"

Output

Element 30 is present: true

2 Check if Element 'banana' is present in String Array using loop

In this example,

We create a string array named fruits with values 'apple', 'banana', 'cherry'.
We use a for loop to iterate through the array and check each element with the specified element 'banana'.
If the element is found, we set a boolean variable found to true; otherwise, it remains false.

Ruby Program

fruits = ['apple', 'banana', 'cherry']
element = 'banana'
found = false
fruits.each do |fruit|
    if fruit == element
        found = true
        break
    end
end
puts "Element 'banana' is present: #{found}"

Output

Element 'banana' is present: true
